The comma is relatively new to the punctuation family (couple hundred years old), so let's go back even farther than that. Jim has a farm and he wants to tell someone he owns this farm, so he's going to say "Jim's farm", right? Wrong. There was no such thing as ('s) to show possession. He would have to say "Jim his farm" to show possession. Fast-forward a couple hundred years and people start to say that doesn't make since, so they changed "Jim his farm" to "Jim's farm" replacing the (hi) in his with a comma. Thus the comma was created.
The funny thing about this is that women did not own anything back in the days, so you would never say "Jenny her farm" and therefore ('r) was never created. Think about it further and when someone shows possession for a female (jenny's farm) they're actually saying (Jenny his farm) replacing the (hi) in his with a comma.
If we wanted to be politically correct it should be:
Jenny'r farm
And
Jim's farm
